Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gas hoods, and specifically to a gas hood structure of a new type of electrocatalytic oxidation reactor. Background Technique
[0002] As an "environmentally friendly" technology, electrochemistry has been widely applied in various environmental protection fields such as sewage treatment, waste gas treatment, and sludge treatment in the market. Among them, electrocatalytic oxidation technology is a type of electrochemistry. During the sewage treatment process, an electric current acts on the reactor electrode plates, and under the action of a catalyst, it reacts with hydroxide ions in water to produce hydroxyl radical strong oxidants. Pollutants react with the hydroxyl radical strong oxidants to generate gases such as water, carbon dioxide, hydrogen, and oxygen, achieving the removal of organic pollutants. For the gases and volatile substances carried by the sewage during the reaction process, when they diffuse into the environment, it seriously damages the local air quality and the health of operators, especially for toxic, harmful, flammable, and explosive gases, whose hazards and destructiveness are even stronger. Traditional electrochemistry reactors operate in an open manner, increasing the ventilation volume and reducing the environmental pollution of waste gas through dilution, but they do not fundamentally solve the problem of removing waste gas pollution sources or hazards.
[0003] This application designs a new type of electrocatalytic oxidation reactor gas hood. The gas hood cover plate is hermetically connected to the outer shell of the electrocatalytic oxidation reactor through fixing bolts around it. The shape of the gas hood is an inverted funnel shape, and a flange is provided at the thin conical opening for connection with the negative pressure extraction pipeline. The gas generated by the reactor is extracted to a flare or waste gas treatment device for centralized treatment. Four observation holes are provided on the side wall of the gas hood, allowing for a 360-degree dead-angle-free observation of the internal situation of the reactor, fundamentally solving the safety and environmental protection hazards of the diffusion of polluting gases such as organic waste gas, hydrogen, and chlorine into the environment.
